ABSTRACT:
Apparatus for detecting thermal radiation emanating from two different intracranial depths in a patient includes a dual-mode transducer having a working surface for placement against a patient's cranium. The transducer includes a first antenna with an aperture adjacent the working surface that first antenna being tuned to a first frequency and producing a first output signal indicative of thermal radiation received within an antenna pattern extending a selected first distance from the working surface and a second antenna having a second aperture adjacent to the working surface within the first aperture. The second antenna is tuned to a second frequency and produces a second output signal indicative of thermal radiation received within an antenna pattern extending a selected second distance from the working surface, the second distance being shorter than the first distance. The two output signals are coupled to a receiver/control unit which thereupon monitors and displays the temperature at the two intracranial depths.
